如何使用Pivot或Unpivot獲得此結果

我有一個查詢，其中我正在獲取像這樣的結果，並且正在創建下面的結果集。但我需要在最後一個如何使用Pivot或Unpivot獲得此結果

SELECT DISTINCT      LEFT(DATENAME(m, CONVERT(DATE, CONVERT(VARCHAR(10), fcp.DateKey))), 3) + ' ' + CONVERT(VARCHAR(4), year(convert(DATE, CONVERT(VARCHAR(10), fcp.DateKey)))) DatePeriod 
     ,OM.HedisOCMKey AS OutComeMeasureKey 
     ,(
      SELECT NumeratorSegmentCnt 
      FROM Fact.HedisOCMSegments omse 
      WHERE omse.SegmentLabel = 'Good' 
       AND omse.HedisOCMKey = OM.HedisOCMKey 
      ) AS Good 
     ,0 AS Fair 
     ,0 AS Poor 
     ,0 AS 'NotCategorised' 
       FROM fact.HEDISReport fcp WITH (NOLOCK) 
    INNER JOIN fact.HedisOCM OM WITH (NOLOCK) 
     ON OM.HEDISReportKey = fcp.HEDISReportKey 
    INNER JOIN dim.ConditionMetric dc WITH (NOLOCK) 
     ON dc.ConditionMetricID = OM.MetricID 
    WHERE fcp.DateKey <= @i_ReportingPeriod

我出來得到如圖所示把像這樣的：

ConditionPrevalenceKey PopulationConditionCnt PrevalencePercent DatePeriod OutComeMeasureKey Good Fair Poor NotCategorised NotTested GoodPercentage FairPercentage PoorPercentage NotCategorisedPercentage NotTestedPercentage GoodRange FairRange PoorRange NotCategorisedRange NotTestedRange DerivedGoodValue DerivedFairValue DerivedPoorValue DerivedNotCategorised DerivedNotTested ConditionMetricName 


18018 252 0.53 Dec-12 34957 35 0 0 0 217 13.89 0 0 0 86.11 Good Fair Poor NC NoData >= 1 0 0 NotCategorized NotTested Chlamydia Screen

那麼我怎樣才能讓我的結果集，像這樣的：

year Legend percent count Derived value field 


Dec-12 Good 13.89 35 >= 1 

Dec-12 Fair 0 0 0 

Dec-12 Poor 0 0 0 

Dec-12 NC 0 0 0

建議我？

我會使用UNPIVOT。在stackoverflow上，UNPIVOT上有很多線程。這是一個example。這是非常相似的another。

這裏是一個普遍開始解決您的特定問題使用UNPIVOT：

SELECT [DatePeriod] , 
     [OutComeMeasureKey] , 
     [Legend] , 
     [Percent] 
FROM (SELECT DISTINCT 
       LEFT(DATENAME(m, CONVERT(DATE, CONVERT(VARCHAR(10), fcp.DateKey))), 3) + ' ' + CONVERT(VARCHAR(4), YEAR(CONVERT(DATE, CONVERT(VARCHAR(10), fcp.DateKey)))) DatePeriod , 
       OM.HedisOCMKey AS OutComeMeasureKey , 
       (SELECT NumeratorSegmentCnt 
       FROM Fact.HedisOCMSegments omse 
       WHERE omse.SegmentLabel = 'Good' AND omse.HedisOCMKey = OM.HedisOCMKey 
       ) AS Good , 
       0 AS Fair , 
       0 AS Poor , 
       0 AS 'NotCategorised' 
     FROM fact.HEDISReport fcp WITH (NOLOCK) 
       INNER JOIN fact.HedisOCM OM WITH (NOLOCK) ON OM.HEDISReportKey = fcp.HEDISReportKey 
       INNER JOIN dim.ConditionMetric dc WITH (NOLOCK) ON dc.ConditionMetricID = OM.MetricID 
     WHERE fcp.DateKey <= @i_ReportingPeriod 
     ) AS sourcetable UNPIVOT ([Percent] FOR Legend IN (Good, Fair, Poor, [NotCategorised])) AS unpvt
